Aluminum bumper brackets, a new offering

Motorhead- I'm sure you know, but there are two different bumper support setup's used in 74. Most 74's did not come with the bumper filler and shocks. Most came with the brackets and the bumper already tucked in. 75 and 76 had the filler and shocks, but in 76 then you had the "Light" cars with bumpers that were shaped different with more holes located in slightly different positions. Just some info
I appreciate this info more than you can imagine. I have been trying to figure out the differences in these years of 74-76. I am trying to accommodate all of the options for my customers. Thank you!
